AUXILIARY Application filed The purpose of the invention is to provide:

a suction-opened spring-closed automatically troduces supplemental air in aproperly and uniformly distributed manner to mingle with the fuel charge and to aid in vaporizing the charge, whereby to duction into the cylinders.

Our primary aim is to generally improve upon additional air supply devices of this general classification by providing a struc- 5 ture which is characterized by unusual simthe carbureted fuel charge to better fulfill the plicity in structural arrangement and parts, a device which serves to better proportion the amount of additional air in relation to the speed of the motor, and otherwise co-act with requirements of a valve of this species.
